On the mpc5200b the ccr register is 32 bits wide while on the
mpc5200 it's only 16 bits. It's up to the driver to use the
correct format depending on the chip it's running on.

The 5200b also offers some more registers & status in AC97
mode. Again, if not running on a 5200b the driver should not
use those.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
